.MP4 versus .M4A
MP4 is for video format to play .mp4 video on players.
M4A is for audio format to play. M4a audio on MP3 players.
M4A stands for MPEG 4 Audio and is a filename extension used to represent audio files.
The existence of two different filename extensions, .MP4 and .M4A, for naming audio-
only MP4 files has been a source of confusion among users and multimedia playback
software. Apple Inc. started using and popularizing the .m4a filename extension, which
is used for MP4 containers with audio data in the Advanced Audio Coding (AAC) or its
own Apple Lossless (ALE, ALAC) formats. Most software capable of creating MPEG-4
audio will allow the user to choose the filename extension of the created MPEG-4 files.
